We develop nonsmooth optimization techniques to solve$H_infty$synthesis problems under additional structural constraints on the controller. Our approach avoids the use of Lyapunov variables and therefore leads to moderate size optimization programs even for very large systems. The proposed framework is versatile and can accommodate a number of challenging design problems including static, fixed-order, fixed-structure, decentralized control, design of PID controllers and simultaneous design and…

A numerical method for solving the H∞ synthesis problem as an unconstrained, nonsmooth, nonconvex minimization problem and the optimization variables consist solely of the entries of the output feedback matrix.

Nonsmooth structured control design

This work proposes a systematic way to design H∞-optimal controllers with fixed structure using local optimization techniques and applies non-smooth optimization techniques to compute locally optimal solutions.

Direct Synthesis of Fixed-Order ${\cal H}_{\infty}$ Controllers

This work proposes an algorithm for noniterative direct synthesis (NODS) of reduced order robust controllers that involves initial computation of two positive-definite matrices via full-order convex LMI conditions to directly obtain a suboptimal convex formulation for the fixed-order controller.

H∞mixed-sensitivity design with fixed structure controller through Putinar positivstellensatz

A novel approach for mixed-sensitivity design with fixed structure controller by introducing the feasible controller set as the set of controllers, within a given class, which guarantees fulfillment of requirements on robust stability and nominal performances for the closed loop system.
